In this paper, we use Kurucz stellar atmosphere model and black-body model to fit for the observational data in ultraviolet, optical, near-IR and IRAS bands for the 22 Herbig Ae/Be stars, and use the method of energy balance to analyze the ratio of the energy dissipation of the central stars and the energy reradiation from the dust shells statistically, we conclude that the morphological type of the circu-mstellar dust shell of Herbig Ae/Be star is disk-shaped.
By assuming that the radio power of AGN jetsmainly comes from the energy of black hole spin and adopting the jet-disk coupling picturesuggested by Falcke and Biermann (1995), we estimated the maximum radio luminosity ofAGN jets. In comparison with the observed data of radio loud sources in PG quasar sample,we proved that radio-loud quasars are such a kind of objects that they not only have verysmall inclination angles, but also have very rapidly spinning supermassive black holes intheir centers.
The most important aspects emerged from the temporal and spectral analysis of the X-ray data,including power spectral density,structure function,inter-band time lags,shifts of synchrotron peak energies,and spectral evolution are focused.
Finite energy band-limited functions are reconstructed iteratively
When, in addition, the Tolimieri-Orr condition A is satisfied, the minimum energy dual windowoγ ε L2(?) can be sampled as well, and the two sampled windows continue to be related by duality and minimality.
Finite-energy high frequency signals, band-pass frequency signals, and band-stop frequency signals are characterized.
We use the analytic tools such as the energy, and the Laplacians defined by Kigami
On Global Finite Energy Solutions of the Camassa-Holm Equation
If is a ?2-grading of a simple Lie algebra, we explicitly describe a-module Spin0 () such that the exterior algebra of is the tensor square of this module times some power of 2.
The operation adj on matrices arises from the (n - 1)st exterior power functor on modules; the analogous factorization question for matrix constructions arising from other functors is raised, as are several other questions.
Let q be a power of p and let G(q) be the finite group of Fq-rational points of G.
We prove a Tauberian theorem of the form $\phi * g (x)\sim p(x)w(x)$ as $x \to \infty,$ where p(x) is a bounded periodic function and w(x) is a weighted function of power growth.
A new C*-algebra of strong limit power functions is proposed.
